Description

The invention relates to a fastening device for to be arranged on a frame structure planar components, in particular solar modules, comprising a first and a second, spaced apart, horizontally and parallel to be arranged on the frame structure support rail on which a component in the region of its opposite edges can be fixed.
Large-area components, such as solar modules or solar panels, etc., are usually arranged outdoors, whether freestanding or on house roofs, on a frame structure. The frame structure is usually anchored in the ground or on the roof itself and consists, for example, of corresponding side guides, formed of suitable profile rails, on which the components are fixed by means of a suitable fastening device. Such a fastening device usually comprises two parallel and spaced apart to be arranged on the frame structure rails extending between the frame mounting portions. On these rails, the components are fixed on the edge or with fastening means. For this purpose, usually threaded fasteners are used, so suitable brackets that are screwed to the respective rail and in a suitable manner, often via screw, fixed. D. h., Each individual component is individually fastened or screwed, which is very expensive during assembly, as well as in the context of disassembly, for example, if a component is to replace because of a defect.
A contrast much simpler mounting option is in the post German patent application 10 2006 053 831 described. There is a simple trained holding plate is used, which is inserted and rotated in an undercut groove on a rail, and having a holding portion with which a component is overlapped laterally on its frame. The retaining plates are merely inserted or screwed, which allows a very simple fastening and thus building the entire arrangement, on the other hand, an exchange is very simple. Prerequisite for this type of attachment is that each component has a frame that is overlapped by the holding part. For example, in the case of a solar module, it would not be possible to mount the holding part directly on the upper glass plate, as this could otherwise be damaged. The presence of the frame and the fact that the retaining plate is arranged in the mounting position between the frame, so that they are spaced in the mounting position by several millimeters to centimeters, is disadvantageous in so far as this is the maximum possible, laid on the given base active area is reduced to solar modules. For example, referring to the surface of a house roof, this inevitably given distance between the individual modules, be it in the vertical or in the horizontal direction, leads to the fact that it is possible to lay with far less module area than the base area would be.
Out DE 10 2004 044 103 A1 is a device for fixing solar modules to mounting profiles known. The solar modules are pre-assembled by means of multi-part module screw terminals to form a plurality of solar modules having solar module unit on corresponding mounting profiles. These preassembled solar module units are then attached via additional multi-part screw terminals on the roof side arranged mounting profiles that run along the roof pitch.
The invention is thus based on the problem to provide a fastening device that allows a very closely adjacent arranging flat frameless components, in particular of solar modules.
To solve this problem, the invention provides a fastening device, in particular for solar modules, comprising a first and a second, spaced apart, horizontally and parallel to be arranged on the frame structure supporting rail, to which a frameless component in the region of its opposing upper and lower component edges can be fixed on the underside of each frameless component in the region of the side edges of individual profile elements are arranged with a projecting to the side retaining web, which serve the connection with the support rails, and that for connecting a profile element with at least one support rail a holding element with a first attachment portion for attachment to a Fastening region of the support rail and a second mounting portion with two projecting to both sides holding portions, which in the assembled position, the opposite holding webs of two is intended to overlap next to each other to be determined components.
In the fastening device according to the invention only frameless components, so for example solar modules are used, unlike in the prior art, where components are provided with a comprehensive framework. In contrast, in the fastening device according to the invention arranged on the components only on the underside of profile elements are provided, the minimum, preferably about 1-2 mm, protrude beyond the side edges of the components and so avoid z. B. in the case of solar modules whose glass panes together can lie. The profile elements have a holding web, which is preferably directed towards the side edge, which interacts with a holding element, which in turn is releasably secured to a carrier profile rail. The jetty could but z. B. are also vertically on the edge of the profile element, so that its upper free edge cooperates with the holding element. The holding element itself has a first attachment portion for attachment to the support rail and a second attachment portion, with which it cooperates with the respective holding web of two adjacent components. D. h., The fixation of the components to the support rails and thus the frame structure is carried out exclusively in the area below the components after the clamping engagement of the holding sections on the holding webs of the profile elements in the area below the components. These can therefore be positioned in maximum approach to each other, ie, they can lie directly against each other, and consequently also touch each other. This consequently makes it possible to make maximum use of the existing base area, since there is no compelling spacing of the components when using the fastening device according to the invention because of existing comprehensive frames or between the components to be set holding elements. Furthermore, the arrangement of the profile element or elements on the underside of the component does not reduce the active area of the component embodied as a solar module, unlike in the case of comprehensive component frames, in which the frames overlap the upper side of the component and thus reduce the active area.
In principle, it is possible to attach a component to the first and the second support rail via such holding elements. However, according to the invention, it is particularly expedient to fasten the components only to the first support rail via such holding elements and to provide a different holding possibility for fixing to the second support rail, which also the presence of the located below a component holding web and profile element for a terminal plug in conjunction with a uses corresponding terminal receiving the second support rail, as will be discussed below.
The component underside arranged profile elements are advantageously vertically and horizontally extending rails that are either mitred cut in the region of their corners by means of preferably inner corner connectors connected to each other or via corresponding corner connecting profile connector, which then form the profile elements after the support rail fixation in the area the corners take place, are interconnected. The rails have a stabilizing function in any case, according to the invention, the components are frameless. This prevents excessive bending of the components in the assembly position, be it in the vertical or in the horizontal direction.
The holding element itself is essentially T-shaped and has a longitudinal limb and a transverse leg which is arranged on the latter and forms the two holding sections, d. h., The transverse leg engages on both sides via the corresponding holding webs of the adjacent profile elements. The respective support rail on which the holding element, which is strong in the region of the longitudinal and transverse leg a few mm, preferably 1-5 mm, in particular 2 mm, is fixed, preferably has an undercut groove as the attachment area, while the first attachment portion on Holding element is designed as a hook portion over which the retaining element in the undercut grooves in the mounting position can be hooked. Preferably, the groove is formed as a double undercut T-groove and the hook portion of the groove shape according to T-shaped. This allows for easy insertion, the hook portion is only inserted from above into the groove and then twisting to secure it securely. The holding element is longitudinally displaceable in the groove, so it can be readily used at any point and pushed accordingly in position and thus encroachment on the retaining web of a profile element.
As part of the assembly, a first component is fixed, after which the one or more holding elements are positioned on him under attack over the retaining web and then the second component is pushed. In order to avoid that in this case two adjacent components with their side edges, formed essentially by the exposed glass plate edge in the case of a solar module, when pushed together directly beat each other - if this is not already ensured by the optionally laterally by about 1-2 mm projecting profile elements - Is expediently provided on a holding element at least one in the mounting position, the adjacent profile elements gegenlagernder stop on which abut both components over their respective profile elements and on which they and thus the components are spaced defined. The stopper is designed and positioned so that the profile elements run against it and at the same time the side edges of the components are positioned in a desired as close as possible contact each other.
After solar modules are usually arranged at an angle, an expedient development provides for a preferably web-shaped stop for the profile element (s) arranged in the region of the lower component edge on the first fastening region of a carrier profile rail. When placing a This component, for example, first fixed in the region of its upper edge in the preferred manner described below, after which the component is lowered with its lower edge until the or the profile elements rest on the support rail and wegbegrenzt lie against the web-shaped stop, on the other Slipping is prevented, after which takes place in a simple way the fixation on the holding elements.
As described, it is basically possible to fix the components in the region of both the lower and the upper component edge using a described holding element. However, an expedient embodiment of the invention provides for this only in the region of the lower edge of the component for fixing to a first support rail and to provide a different mounting option in the region of the upper edge of the component for attachment to the second support rail. For this purpose, the optionally second support rail has a second attachment area in the form of an open to the component edge, substantially C-shaped receiving groove into which the holding web of or there profiled elements, overlapped by a leg of the receiving groove engages. Here, a simple Steckklemmhalterung by the edge of the profile element is inserted with the projecting retaining web in the open receiving groove, so that the holding web is overlapped by the leg of the receiving groove and fixed against lifting. D. h., As part of the assembly, only the profile element section is to be inserted with the holding web in the receiving groove from below, after which the component is lowered until the or the lower profile elements sit on the lower support rail and run against the local stop web, which immediately the fixation can be done via the retaining element.
A particularly expedient refinement provides that the first and the second attachment region are formed on each support rail, that is to say the first and second attachment regions. h., The rails are so far identical design so that a total of only one profile must be kept in stock, which offers the two mounting options according to the invention.
In this case, according to an expedient development of the invention, the first fastening region is arranged higher than the second fastening region in the assembly position. As described, the fixation via the profile elements always takes place in the region of the side or vertically projecting holding web. This is relative to the underside of a component, as revolving, always in the same position. If the first fastening region now lies higher than the second fastening region, then this inevitably leads to the component being arranged somewhat higher in the lower edge region where it is arranged on the first fastening region than in the upper edge region, where it is on the second fastening region is fixed. This now offers the particularly advantageous possibility of overlapping two superimposed components slightly with each other. Because of the height-wise offset of the two attachment regions, the upper edge region of a lower component can be pushed and arranged below the lower edge region of an upper component. D. h., The lower edge region of the upper component overlaps slightly the upper edge region of the lower component, so that a quasi-scaled arrangement, seen in the vertical direction, with simultaneous possibility of an almost immediately adjacent arrangement in the horizontal direction can be realized. This now offers the possibility to use such components virtually as a roof tile substitute, so therefore to cover the roof itself about these components (in-roof version).
In particular, in such an arrangement, but also when the components are not offset and overlapping, but are arranged parallel to the plane, it is expedient to provide at the lower in the mounting position horizontally extending and designed as a profile rail profile element in the optionally provided profile connector optionally continuing sealing element in which, in the assembly position, the edge of the component arranged below it rests. This advantageously allows a seal in the region of the horizontal gap between two components.
In order to provide a sealing possibility also in the longitudinal direction, in order to avoid that due to the capillary gap resulting in each other (almost) touching components in the region of the longitudinal side edges moisture drops down, is expediently between two opposing profile elements with respect to the mounting position in Provided longitudinally extending and extending below the transition gap between two adjacent components, optionally also the stiffener serving profile component. This profile component may for example be made of plastic or metal and extends over the length of an elongated, rectangular component (the length of which is, for example, about 1.7 m, while the width is about 1 m). The profile member extends just below the resulting narrow gap and receives dripping water passing over it and discharges it down where it can be derived as a result of either the continuation of the profile member to the next member or the overlapped assembly.
In any case, a laterally open receiving or clamping portion is expediently on each profile element for a clamping portion of Sealing element or the side leg of the profile component provided. This can be a simple fixation of the sealing element, for example a rubber sealing element, which is sufficiently deformable and, for example, a sealing lip or the like, or the profile component, which can be designed as a metal part or as a sufficiently rigid plastic part, can be achieved.
In order to ensure a secure support of the profile elements on the support profile rails, a tooth or groove-like surface structure is expediently provided on at least part of the bearing surfaces of the profile elements.
Furthermore, a profile element, in particular as far as this is designed as a profile rail, have at least one hollow chamber in which a stiffening element is arranged. This z. B. of metal, preferably aluminum (such as the profile elements itself) existing stiffening element serves to stiffen the entire component in order to avoid longitudinal or transverse bending.
In addition to the fastening device itself, the invention further relates to a component group, in particular solar module group, which is arranged on a frame structure in which a plurality of juxtaposed, frameless components are assembled using a fastening device of the type described in a composite. It is only necessary in the component group according to the invention to provide an anti-theft device to the outer components, since the inner components on the holding elements and the preferred clamping plug fixation on the other edge of the component are not removable and not detachable without loosening the anti-theft device.
Further advantages, features and details of the invention will become apparent from the embodiment described below and from the drawing. Showing:

1 shows in the form of a schematic diagram one on a house roof 1 arranged component group 2 , comprising only exemplary six components 3 , z. B. in the form of solar modules 4 comprising a plurality of power generating solar cells. For holding the solar modules 4 is a frame construction 5 provided, comprising two here vertically extending rails 6 that have appropriate roof mounts 7 fixed on the roof side. About not shown fastening means are two support rails 8th on the rails 6 of the frame construction 5 arranged. The two support rails 8th run spaced and parallel to each other and traverse the rails 6 horizontal. They are part of a fastening device for the solar modules 4 , which will be discussed below, in turn, via suitable profile elements and holding elements on the support rails 8th are attached. It should be noted at this point that of course far more than six solar modules 4 next to each other and more rows can be arranged one above the other, depending on the size of the assignable surface.
2 shows in an improved view the frame structure 5 with the rails 6 as well as arranged thereon, usually screwed support profile rails 8th of which three are shown in the example shown. Two support rails each 8th serve to fasten a component 3 , ie one solar module each 4 , so that, based on such a solar module 4 , one supporting rail each 8th the first support rail 8th and the other support rail 8th the second support rail 8th represents. The supporting profile rails 8th are all run the same, 3 shows a sectional view through such a support rail 8th , To be on such a support rail 8th two vertically to each other subsequent components 3 or solar modules 4 to be able to fasten, as this, starting from the example according to 2 , at the middle support rail 8th The case is, are on each support rail 8th formed two attachment areas, a first attachment area 9 consisting of a here T-shaped, so on both sides undercut groove 10 together with a support surface 11 and a stop limiting this 12 , as well as a second attachment area 13 in the form of an open towards the side, substantially C-shaped in cross-section receiving groove 14 holding a lower support leg 15 and an upper leg 16 and a groove bottom 17 having. The two attachment areas 9 and 13 are obviously offset in height, the mounting area 9 is higher than the mounting area 13 , In 3 is further the attachment of a support rail 8th on a rail 6 of the base frame shown. These are two lateral T-slots 18 provided in the appropriate clamping plates 19 engage, in turn, not shown on the mounting screws on the respective rail 6 are attached.
4 shows a partial view of a component 3 , here a solar module 4 in the area of one of its edges, which may be either a side edge or the top or bottom edge of the component. On the bottom 20 of the solar module 4 is a profile element 21 arranged, usually glued, including the profile element 21 a flat top holding leg 22 having. The profile element 21 , which is designed as a support rail also as a hollow chamber profile made of metal, preferably aluminum, also has a profile section 23 in the region of its lower end, with a laterally projecting retaining bar 24 , which is parallel to a lower bridge 25 of the profile section 23 runs. Also planned is another jetty 26 forming a groove 27 , which serves to receive a stiffening and sealing profile component, which will be discussed below. In the hollow chamber can extend over the length of the profile element 21 , which is preferably a rail, extending stiffening element (eg made of metal) can be arranged.
The 5 and 6 now show the attachment of a solar module 4 in the area of the lower component edge on a support rail 8th , Below the solar module 4 are in the example shown a first profile element 21 in the form of a over the entire vertical length of the solar module 4 extending profile rail 28 arranged. A not shown in detail, also as a profile rail 28 trained profile element 21 is on the horizontal side 29 arranged. Both rails 28 are via a profile connector 30 , which continues the respective profile rail form, and also a profile element 21 forms, connected. The profile connector 30 as well as the horizontally extending, not shown in detail rail 28 each have a profile section 23 on, at the stop bridge 12 of the first attachment area 9 abuts. This is the movement of the inclined solar module in the mounting position 4 limited to the bottom.
To fix a retaining element 31 used that, see 6 , a lower T-shaped hook portion 32 has, in which a longitudinal leg 33 followed, in turn, a transverse leg 34 is arranged, the two lateral holding sections 35 forms. There are also two lateral stops 36 intended.
The holding element 31 in the area of his longitudinal leg 33 flat, ie sheet-like formed with a thickness of 2-5 mm, is now in a, based on the 5 and 6 90 ° twisted position with the hook portion 32 from above into the groove 10 inserted and then by 90 ° in the in the 5 and 6 rotated position shown. Then the hook section 32 against the solar module 4 pushed until the two stops 36 at the lower bridge 25 of the profile section 23 of the profile connector 30 abutment, wherein in this position then the one holding section 35 the jetty 24 has overlapped flat, so about this in connection with the hook section 32 a clamping attack is realized, the lifting of the solar module 4 prevented.
For mounting a next solar module 4 this is in a corresponding manner with its lower edge region or the profile elements provided there 21 (Rail 28 and profile connectors 30 ) on the first attachment area 9 put on and against the stop bar 12 guided and then against the already arranged solar module 4 pushed. Here, the corresponding profile section is running 23 of the profile connector located on the adjacent solar module side 30 , which in the embodiment shown in the region of the profile section 23 a short vertical bridge 53 has, against the other side of the attacks 36 the already set holding element 31 , the local jetty there 24 of the profile connector 30 gets under the second holding section 35 of the holding element 31 pushed, so that too this component 3 then secured in place. The embodiment of the retaining element 31 , in particular the length of the stops 36 , is dimensioned so that the two longitudinal narrow edge projections 37 the adjacent profile elements 21 , which protrude laterally by about 1-2 mm and prevent the glass edges of the module glass plates can abut each other, only minimally spaced from each other, or directly adjacent to each other.
While the 5 and 6 show the fixation of the lower edge of the component shows 7 the fixation of the upper edge of the component. Below the solar module 4 is also in the region of the upper edge of the component not shown here in detail, parallel to the edge of the component edge 38 extending profile element 21 in the form of a profile rail 28 arranged, in turn, via a profile connector 30 , which in turn is a profile element 21 represents, with the vertical profile rail 28 connected is. For mounting a solar module 4 Now, first the bottom edge of the profile connector 30 and the horizontally extending rail 28 with the respective profile sections 23 on the support leg 15 of the second attachment area 13 set and then pushed a piece up until the profile section 23 in the C-shaped receiving groove 14 is taken and by their thighs 16 is overrun. Then, the lower component edge on the first mounting area 9 the underlying support rail 8th put on and against the attack 12 led as regards the 5 and 6 described. In any case, however, remains the profile section 23 of the profile connector 30 and the horizontally extending rail 28 in the C-shaped receiving groove 14 , so that here too a safeguard against unintentional lifting is given. A further fixation in the region of the upper edge of the component does not take place, only against a horizontal displacement, as will be discussed below.
In 7 is also shown as a first solar module 4 with a second solar module arranged above it 4 in terms of location. At the upper solar module 4 is, see also 6 , a sealing element 39 arranged, which extends over the entire horizontal width. It is on the horizontally extending profile elements 21 that is the profile connector 30 and the horizontally extending, not shown rail 28 arranged. The fixation takes place in the groove 27 , which serves as a clamping groove. The sealing element 39 has a corresponding slot 40 on, over which a clamping section 54 is formed in the groove 27 is inserted. Furthermore, a downwardly projecting sealing lip 41 and a sealing loop 42 provided on the inside.
As 7 shows, becomes the solar module 4 under the sealing element 39 pushed, with the sealing lip 41 deformed and sealing at the top 43 of the lower solar module 4 rests. Over this a line seal in the horizontal direction is achieved. The upper solar module 4 overlaps over the lower solar module 4 so that a shingled, shingled arrangement results. Depending on how far the lower solar module 4 in the direction of the upper solar module 4 can be pushed over the solar panel 4 also the sealing loop 42 be compressed so that there is also a line seal.
As 7 further shows, runs a profile component 44 , which, as will be discussed below, in the vertical direction below the transition slot between two adjacent solar modules 4 extends, against the sealing loop 42 , This profile component 44 can have a lead 45 (For example, an inserted pin), the stop bar 12 engages, be fixed.
Such an arrangement of a sealing component profile component 44 between two profile elements 21 , here for example two profile rails 28 , two adjacent solar modules 4 shows 8th , The profile component 44 , For example, plastic, has a cross-sectional groove shape. It serves to seal the between the components 3 optionally remaining gap 48 , About two side sections 46 grab it in the grooves 27 the profile rail 28 one. Visible is the recess resulting from the channel shape 47 below the optionally given very narrow gap 48 between the immediately adjacent side edges of the two solar modules 4 or the edge projections 37 , Anything about this gap 48 penetrating moisture accumulates in the recess 47 and, after the assembly is at an angle, runs down to where it can be removed. For this purpose, the deepening 47 slightly above the underlying solar module open (in this area would optionally be the sealing element 39 to interrupt). As shown by dashed lines, it is also conceivable on the profile component 44 a sealing bar 49 to form, for example, from a soft plastic material, in the mounting position in the gap 48 Sealing this lies.
As 8th can also be seen, has a profile element 21 , here at the lower jetty 25 shown a gearing 50 on, on the improved support on a support rail 8th is reached. Shown are also two drip edges 51 on the holding leg 22 ,
The fixation methods described allow it, two superimposed components 3 or a component group 2 still to move horizontally. To the entire component group 2 or to fix a horizontal component row against this, in each case the outermost right and leftmost component 3 a row in the region of its lower component edge and its upper edge of the component fixed to the support rail 8th connected, see 9 , For this purpose, a claw-like holding member 52 provided that the vertical web 53 of the profile connector 30 , which provided at its lower end and the part of the local profile section 23 is, overlaps, and a suitable fastening screw and nut is the holding member 52 then in the groove 10 anchored, over which an anti-theft device can be built.
Instead of an arrangement of profile connectors 30 , the self profile elements 21 form, in the corner of a component 3 it is also possible, the rails 28 Miter cut and connect via an inside simple corner connector by pressing. A bottom frame then becomes only four rails 28 formed with the inner corner connectors.
